Recent palaeoanthropological investigations have been initiated in the Arabian peninsula to determine how this key region fits into our understanding of hominin evolution, adaptation, and dispersal. The Arabian peninsula is often depicted as a key geographic route for hominin dispersals in 'Out of Africa' models, although primary evidence is rarely cited. Recent re-investigation and synthesis has shown the presence of significant Palaeolithic assemblages have been identified in many parts of the peninsula, including in areas near the Strait of Bab al Mandab.

The presence of Oldowan-like and Acheulean assemblages in Arabia may reflect at least two early dispersals outside of Africa. Acheulean localities are particularly abundant on the Arabian peninsula, and variations in stone tool manufacturing techniques and tool type frequencies may reflect temporal changes in assemblages. In addition to Lower Palaeolithic sties, numerous Middle Palaeolithic localities have been identified on the Arabian peninsula. The presence of Middle Palaeolithic assemblages is particularly important for our understanding of key events in hominin evolution, including the emergence of anatomically modern humans, the development of more complex adaptations, and the dispersal of modern humans outside the African continent. Interestingly, the Lower and Middle Palaeolithic sites are associated with moist and arid conditions, providing us with the potential to understand how humans adjusted to environmental change.
